This invention relates to antifriction bearing cages and comprises all. the features The invention, in its broader aspects, is not necessarily limited to the specific form selected for illustrative purposes in the accompanying drawings in which 7 F i 1 is a side View of a portion of a circular blank from which one of the cage sections is formed.

Fig. 2 is an inner side view of a portion of one of the cage sectionswith one fastener inserted.

Fig. 3 is a cross sectional View of a portion of one of the cage sections prior to a subsequent forming operation.

Fig. 4 is across sectional view of a portion of one of the completed cage sections,

- the section being taken between two adjacent ball pockets.

Fig. 5 is a similar cross sectional View taken through one of the pockets.

Fig. 6 is a cross sectional view of a portion of one cage section with one of the fastening devices inserted.

" Fig. 7 is a cross sectional view of apor-v tion of the completed cage. 1

Fig. 8 is a cross sectional view of a portion of a completed ball bearing with the cage in place.

The cage comprises a pair of opposed having a continuous annular side wall 12, a set of inwardly extending legs or projections 14 at its outer edge, and a set of inwardly extending legs or projections16 at its inner edge. The outer legs or projections 14 terminate in flat abutment faces 18 and the inner legs or projections 16 terminate in flat abutment faces 20. The corresponding faces of. one ring abut against tends radially outwards from those of the other, in the preferred jconstruction. I The rings have registering pockets for rolling. elements, the pockets being formed by the side edges 22 and 24 of the legs or projectionsll and 16. In the case of a ball bearing, the edges 22 and 24 arespherical segments conforming to the balls 26. When both sets of-faces 18 and 20 abut, as ispreferable, closed compartments are formed between the balls, usable to contain lubricant. Oneset of legs or projections on" each ring, preferablythe outer set 114, is notched as indicated at 28 andthe side wall 12 of eachring has a series of straight sided openings 30. The notches 28 of one ring register with the notches of the other ring and the openings '30 of one ring register. with the openings30 of the other. Also the notches are in radial alignmentwith thefiopenings. The rings are secured together devices 32, each comprising a fiat body portion withreduced end extensions 34, shoul-v ders 36, and a central lug. or key 38. Each key or lug 38, in the completed cage, exthe body portion and is arranged to enter and fill a pair of registering notches 18, thus locking the rings against relative rotation or weaving.

The extensions 34 are also radially arranged and venter registering openings 30 in the ri t e exten i being et d w to hold therings'together with their side; walls against the shoulders 36. Preferably the fastening 'devices' are v of suficient radial width to. fillth'e.spacesbetween' the outer and innersetsiof legs or'projections let'and by fastening 16, 'thereby'bracingthe latter and forming partitions" in the compartments between ad- 7 j a'cent ball pockets Hence-thefasteners conrings 10 of angular cross section, the section preferably being that of'a U, and each ring a stitute braces as wellas rivetsand keys.

P Ze sM z-and 24 e he ba so Theicagezrings are desirablyformed by pressingroperations on an aluminium alloy pockets are desirablyswaged as by a series of ball-ended dies having a radius a very 7 little larger than the balls to be used in the ring with respect to the dies and prevent distortion. In assembling the rings, the fasteners are first applied to one ring as inclicated in Fig. 6. The lugs orkeys 38 and the end extensions 34:, in conjunction with the notches 28 and the openings 30, then hold the fasteners in proper position to re ceive and locate the other ring. Fig. 8 indicates a completed cage applied'to a ball bearing having an inner race ring 42 and an outer race ring 44:.

I claim:

1. In an antifriction bearing, a cage comprising opposed rings of channelled cross section abutting against one another at their edges and having registering pockets for rolling elements, and a device comprising a combined rivet and key fastening the rings together between adjacent pockets and interlooking with said rings at their abutting edges, for'holding them against relative ro tation; substantially as described.

2. In an antifriction bearing, a cage comprising opposed rings having registering pockets for rolling elements and registering notches between the pockets, and fasteners passing through the rings for securing them together and each fastener having a key lug entering the registering notches to hold the rings from relative rotation; substantially as described.

3. In an antifriction bearing, a cage comprising opposed rings having registering pockets for rolling elements, the rings abutting against one another between the pockets and having registering notches in the abutting portions, the rings having reg istering openings, and fastening devices passing through the registering openings and having lugs entering the registering notches; substantially as described.

4:. In an antifriction bearing, a cage comprising opposed rings having pockets for rolling elements, the rings having continuous side walls and inwardly extending edge projections abutting against one another between the pockets, the abutting edge projections having registering notches and the side walls having registering openings, and fastening devices passing through the registering openings and having lugs entering the registering notches; substantially as described.

5. In an antifriction bearing, a cage comprising opposed rings having pockets for rolling elements, the rings having continuous side walls with inner and outer sets of projections between the pockets, the outer projections of the rings abutting against one another and having registering notches, and fastening devices in the spaces between the side Walls and the projections and having lugs entering the notches; sub stantially as described 6. In a cage for antifriction bearings, a cage ring fastener having a body portion, reduced extensions at the ends of the body portion, and a key lug projecting from one edge of the body portion;substantially as described.

7. In a cage for antifriction bearings, a cage ring fastener having a body portion,

reduced extension at the ends of the body portion, and a key-lug projecting from one edge of the bodyportion at the center, the

key lug and the reduced extension being flat and lying in the same plane; substantially as described.

In testimony whereof I hereunto afiix my signature. I.
